ANGLE-SEWING ATT ACIMENT FOR SEWING-MACHINES.

Be it known that I, WILLIAM WILSON, a

ton, in the county of Sutfolk and State of "ll/lassachusettsyhave invented certain new and useful Improvements in Angle-Sewing Attachments for Sewing-lVIaehines,-and do hereby. declare the following to be a full, clear, and exact description of the. invention, such as will enable others skilled in the art to which it appertains to make and use the same. This invention relates. to improvements in angle-sewing attachments for sewing machines.

In the manufacture of various articles of leather it is necessary to secure pieces of leather together by a seam passing at an angle through the material, as, for example, in sewing the corners of a dress-suit case.

One object of the present invention is to produce an attachment for a sewing machine y which such operations are facilitated, the attachment being ada ted to support the work at the correct anglbfor the reception of the seam and having provisions for adjust-'- ments by which the angle at which the.wo rk is held, and the distance of the seam from the Specification of Letters Patent.

edge of the work, may be varied to suit the requirements of the work.

Another object of the invention is to produce an improved angle-sewing attachment for use in sewing harness loo s, the attachment being adapted to hold a oop at such an angle that the sewing instrumentalities engage only one margin of the loop, whereby a seam parallel" to the margin of the loo may be sewed on a sewing machine of or( inary form.

The invention consists in the improved angle-sewing attachment hereinafter described, as defined in the claims.

In the drawings, Figure 1 is a side elevation of an angle-sewing attachment embodying the present invention, together with portions of. a sewing machine in connection with which it is used. Fig.2 is alanview of the attachment; and Fig. 3 is a etail plan view on line a:0:, 1. Fig. 4 is a side elevation of a modified form of the attachment, for use in sewing harness loops. plan view of the same form. Figs. 6, 7, 8 and Fig. 5is a 9 are, respectively, a vertical section, a plan, a

side elevation, and a front View, of the loop support.

Patented May 5, 1908 The illustrated embodiment of the invention is constructed as follows 1- 1. which is provided with a socket and atset screw 2 by which it is removably secured to a round arm 3. The arm 3 is held in a clamp 4 which is provided with a stud5 by which it is pivotally secured to a bracket 6- on the upper end-of a vertical stem 7. Nuts 8 on the stud 5 hold the clamp in' adjusted position on the bracket 6, and a screw 9 causes the clam 4 to hold the arm 3 in adjusted position.

In the form shown in Fi s. 1, it and3 the i work rests upon a work'table or 't.1IO8,l3-pla,l36'

stem 7 is adjusta'bly fixed in a vertical recess in a post or support 10 mounted on the frame of the machine, .the stem being fixed in the post IO'by means of a thumb screw 11 which engages the ears 12 on the upper extremity to the post and draws them together so as. to

being of the usual for1n,'wi.th the exception of the resser foot 15 which is arranged with its wor in surface at an angle to the surface of the wor table or throatlate 1, and is se cured to the supporting am actuating mech anism therefor y adjustable means compris ing screws 16 passing throu h slots, shown in dotted lines in Fig. 1, in presser foot and threaded into an extension 17 from they presser-foot bar of the sewing machine. This arrangement permits adj ustthe shank of the ment of both the angle of the face of the presser foot and also the horizontal position of the presser foot with respect to the needle;

By moving the presser foot toward and from the front of the machine the distance of the seamfrorn the edge of the. work may be ad justed. The several adjustments provided in the supporting means for the work-table orIthroat-plate 1 permit the angle of .the work table to be changed without moving the work' table. laterally,flso that the needle and awl may always register properly with the opening or throat 18 in the work table-or To change the angle'gofth'e work ta le, the screw9 and nuts 8 areloosened throatlate.

and also the-thumb screw 11, and the stem 7 is then moved u and down'until the right angle is obtainec, the arm 3 being at the same time moved longitudinally in the clamp 4 so as to maintain the proper relative posi- O which the operator holds the inner, edge of tion of the work table or throat-plate and the needle and awl. l

To facilitate the replacement of the adustment in working position after it'has een removed from the sewing-machine or temporarily thrown out" of operation the stem 7 is provided with a stop collar 19, which is split and is drawn together by a screw 20 so that it may be clamped upon the wor table or throat-plate is swung backto working position the stop 21'en ages the lug 22 so as to stop the work tab s or throatplate in the proper position without attention or readjustment on the part of the operator. The adjustment may also be removed as a Whole by Withdrawing the stem 7 from the post 10 and may then be replaced in 1 pro er position without any readjustment.

, ang e that the needle I slotted at 26 adapted for e iorm of the invention shown in Fig. 4. and the subsequent figures is particularly sewin harness loops, being ada ted to .hold a arness lo op at such an and'awl may engage one margin only of the loop so as' to form a seam parallel with the edge of the strip of leather of which the loop is made and thus secure to ether the fscarfed ends of .the leather. he loo holder com rises a body portion 23 provi ed witha soc etand a set screw 24 by which it may be fixed to 'the arm 3 in place of the work table-1, the means for supportin the loop holder being the same as those by w ich the work table above described is supported. The body 23 of the loop holder is of such size and form as to distend and sub.

stantially l theharness loop, so that if a strip of leather with its ends suitably, scarfed be wrapped about the body '23 its endswill overlap to the right extent to-make theloop of the desired dimensions. The loop holder is provided with an edge. gage 25' against the loop. The body of the loop hpld'er is for the passage of the needle27. of the sewing machine, and is tipped atsuch' an angle, as shown inFigs. 4, 5, and 6, that. the needle when rising clears the lower side of the loop but penetrates the margin'of the upper side of the-loop so as to form a seam therein. r I- The upperside of the body of the loop holder is slotted at 28 to permit the awl to enetrste the work and make the necessary ceding movement. A pin'29 prevents the shuttle thread of the sewing" machine from I 5 falling out of the slot 26 when the worhis reloo filling the loop, portion being mounted at an angle with the assess moved and thethread cut. After one side turned around and the other side sewn. By substituting loop holders I s of different diameters may be sewn, while loops of diiierent widths may be sewn on the same loop holder.
